CASH-REGISTER.

1,004,881. Specification of Letters Patent.

To all whom ii may concern:

Be it known that I CHARLES F. KETTER- mcba citizen of the Il'nited States, residing at ayton, in the county of Montgomery,

and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which I declare the following to' be a full, clear, and exact description.

This invention relates to cash registers, and more particularly to the indicating device thereof.

It has for its object to provide a system adapted to man known types of r bore for procuring a latent ind1cation,am preffltllllfly an indication comprising electric i ts.

More particularly the invention comprises an arrangement in which the usual indicators of a cash register are adapted to control circuits and relays therein, which re lays when energized close a plurality of local circuits, includ' electric lights. I have shown the invention as applied ;to a particular type of macbinehavingrotating indicators, each of which bearajplurality of indicia, but it will be evident that many of the novel features of the invention are adapted for use with other types of registor, such, for example, as the well-known variety of machine having separate recipr, eating tablets for each amount. With these and incidental objects in view, the invention consists in certain novel features of construction'and combinations of parts, the essential elements otwhich are set forth in appended claims and a preferred form of embodiment of which is hereinafter specifically'described with reference to the. drawings which accompany and form. part of this s ecification.

0f said drawings: igure 1 is a transverse section through a machine to which my invention may be adapted, showing the indicatin device and switch controlled thereby. ig. 2 is a diagram of the circuits from the main indicators to the relay coils. Fig. 3 isa diagram of the circuits at the auxiliary indicator, which are controlled by the role 3.

Described in gener terms, the invention in its present embcdiment is adapted "for operated in correspondence with a transac, t1on desired to be entered 1n the machlnc, and a main operatin device, such, for instance, as a crank'or ever, or a cash drawen, '15 then moved to complete the operation of the machine. The machine includes a;plu

rality of rotating cylinder indicators, each.

ha'v'ing numerals from zero to 9, inclusive, on their peripheries, and a circuit-controls ling switch is also movable with each indicator. A lurality of stationary contacts are adapts to be moved over by the switch, said contacts each contrhlling a lrelayl The relays and contacts are arranged in multip arc, in order that they may be ener from a common source of current, su as tract their armatures, and these armatures control a plurality of contacts for local circuits throu h incandescent lights, thereby causing an 1 lamination of certain combinations of lights, depending on the relay energized. The invention as shown is adapted to give what may be termed a monogram indication; that is, one-in which a lurality of numerals may be exhibited in the same area.

I have shown main switches controlling the relay circuits and the light circuits. The switch for the light circuits is adapted -.to be closed only after the relayswitch is closed, and both switches are only closed after the indicator switches are closed. This sequence of operation prevents sparking at the indicator contacts, a'nd also at the relay contacts inasmuch as when these contacts are made there is; no current in the wire, owin to the break at the main switch.

Re errin now more particularly to the drawings, it will be seen that Fig. 1 shows a series of keys 10, carried by a frame 11,

and adapted to move differentially a lever 12, journaled on a bar 13. This lever 12 has pivoted thereto a rack-bar 14, which is also supported by a bar 15, the said her be ing adapted to be raised and lowered by means not a part of m invention, and not shown herein. The 'rac on bar 14 is adapted to gear when depressed with a root: on a segment 16, 3ournaled on a bar 17. The rear end of the segment 16 carries a rack constantly in gee with the indicator operatingbar 18. f is bar at the top thereof, as shown in this figure, has a rack l9gear to a battery. The relays when energized-ah;

segment will be rocked around its pivot 17, moving indicator bar 18 and setting the indicator to position. This movement also carries switch 21 U a position opposite some one of the contacts 22. Further rotation of shaft 23 causes the cam groove 25 to act on roller 26 and reciprocate the counter $20 over the adjusted racks 19. At the beginning of the operation, main switches 37 and 43 are released from pin 51 and allowed to open. At the conclusion of the o ration, pin 51 again closes switches 37 audit} in the order named. When switch 37 is closed, circuit will be made through wires 33, switches 21, contacts 22, wires 29, relays 30, and bacir through wires 31 to the battery. The encr gized rela s will attract th ir armatures 46, causing al the contacts to be brought into electrical connection with the common contacts 45, this occurrin as stated, before the switch 43 is closed. hen switch 43 is then closed, circuit will be made from the generator 4-1 through wire 42, switch 43, wires, common contacts 45, contacts 47, wires 48, lamps 49, wires 50, and common wire 51 back to the generator 41. The proper lamps 49 will thereby be illuminated, and will remain lights-i until a succeeding operation ofthe machine, as main switches 3 and 43 remain closed. between operations. It will be evident that by using the relays and circuits of. Fig. 2 a large saving of ex pense for wire is thereby made, inasmuch as there is only one wire from each indicator position to a relay, while if the indicator c ntacts were controlled directly, from five to fifteen wires would be needed, each wire controlling a separate lamp. It is also true that a much smaller current is needed with the construction shown, as from five to ten volts is am le to ener ize the relays, whereas the usual llo-volt fighting circuit is used for the lamps. This evidently saves a large amount of current which would be wasted in the wires if the lamps were directly controlled from the indicators.

I have shown the usual condenser as shunting the main switch 43 on Fig. 3, this being for the well-known purpose of minimizing the spark. V

While the form of mechanism here shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not intended to can fine the invention to the one form of em bodime'nt herein disclosed, for it is susceptible of embodiment coming within the which follow.
